Gas Laws Investigation

Conclusion:

The results indicate that there is a direct correlation between the Volume and the Pressure exerted within it, at a constant temperature. While there is a relatively large error range in which the data could be found it seems conclusive that a decreasing power trend line is formed as the volume increases. This means that as the volume increases the pressure will decrease at ever reducing rates. These results are very similar and represent the general trends that are believed to be true by the wider scientific community. While this may not mean that there will always be a correlation, although it has yet to be proven otherwise, it certainly helps to support the accuracy of our data. However from Boyles’s law we can tell that the data isn’t extremely accurate. The K1 results, in theory, should all be equal to each other, yet as shown in the data table this clearly isn’t the case. While my average for the K1 values was 9.85xx there was an approximant ±3.25% difference in values*11 which shows how large an inaccuracy there was with the recoding system. However some of this can be accounted for by the change in temperature. While the temperature was set at 3010K it did slightly fluxuate and while it may have only been to no more than one degree it would still make an impact on the invalidity of the data. In this data set looking at the X and Y intercepts has very little value as both the X and Y’s zero values are asymptotic. Practically is helps us little as an intimately small box can never be reached. All this means that from the results we can conclude the nature of the relationship (i.e. that is not an exponential correlation) however the data points are reasonably inaccurate and so could not be used without a further ...

...could have solved these issues. However because of financial and technological difficulties the apprehension of this was not possible. Despite this, the same results can be achieved by repeating the experiment as many times as possible, 10 -12 times would be ideal. This hopefully will help make outliers more apparent in which human error or technical error may have occurred, allowing for their removal and a more accurate result to be achieved. A more accurate program would have allowed much more precision, accuracy and easy reproductively making it by far the most important improvement I would make. My time management during this practical was reasonably effective as I was able to take recordings and repeat it three times with in the allotted lesson. This gave me an extra day in which to write the report, allowing me to submit both the report and the draft on time.
